Today Year Six learnt about how we can test the quality of our fresh water ways with Kathryn from Watercare. We learnt about the common risks to our local waterways - detergent, nitrates, oil, plastic litter and paint.
Next we tested water samples from an Auckland waterway for turbidity (clarity), PH, temperature and nitrate levels.
Lastly we used magnifying glasses to find macro invertebrates in the samples. Who knew there were so many bugs living in the estuary?! Lots of life means healthier water.
Good news! Our results when compared to December 2023 showed that our waterway is healthier than a year ago, as there were less nitrates present. Sadly there is still lots of plastic litter present. We'll think about actions we can take next year to address this when we conltinue our Year 6 Estuary Inquiry.
Thank you to Kathryn and Watercare for the wonderful hands on learning.
